Abstract

Eine Messeinrichtung bestimmt eine physikalische Grösse nach ihrer Erfassung durch Umwandlung in eine digitale Grösse, die vorbestimmten Rechenoperationen unterzogen wird. Eine übergeordnete Prozessoreinheit gibt einen Steuerbefehl zur Inbetriebsetzung der Messeinrichtung sowie ein Setzsignal ab, durch das eine bistabile Schaltung (FF) setzbar ist. Sind die vorbestimmten Rechenoperationen in einer digitalen Prozessor­ einheit (7) der Messeinheit durchgeführt, so wird hierdurch die bistabile Schaltung (FF) zurückgestellt. Eine Verzögerungs­ schaltung (RSB, CSB) verzögert eine Ausgangsgrösse der bistabi­ len Schaltung (FF) um eine vorbestimmte Zeit und sorgt für die Stillsetzung der digitalen Prozessoreinheit (7) nach einer für ihre Überführung in einen Bereitschaftszustand erforderlichen Zeit. Die Messeinrichtung ist insbesondere zur Messung eines Druk­ kes oder eines Differenzdruckes geeignet.
